Audio maker Bose discloses data breach after ransomware attack By 07:47 PM Bose Corporation (Bose) has disclosed a data breach following a ransomware attack that hit the company's systems in early March. In a breach notification letter filed with New Hampshire's Office of the Attorney General, Bose said that it "experienced a sophisticated cyber-incident that resulted in the deployment of malware/ransomware across" its "environment." "Bose first detected the malware/ransomware on Bose's U.S. systems on March 7, 2021," the company added. The audio maker hired external security experts to restore impacted systems after the attack and forensic experts to determine if any of its data was accessed or exfiltrated by the attackers.
